APPARATUS FOR. ENABLING EXTRAG'IS, IlIIEUSIONS, P. DECOCTIONS TO BE OBTAINED IN A ooiv'rmuous MANNER.

To all whom it may concern:

Be it known that I, PAUL Kns'rNnR, c1t1-- a -Zen of the French Republic, residing at Paris, Department of the Seine, in France,

and whose post-oflice address is 34; Rue de Chateaudun, in the said city, have lnvented certain new and'useful Improvements in Apparatus for Enabling Extracts, Infu-' SlOIlS, or Decoctions to be Obtained in a Continuous Manner; and I do hereby de-- clare the following to be a full, clear, andv exact description of the invention, such as for enablin will enable others skilled in the art to which it appertains to make and use the same.

Thls invention has reference to apparatus extracts, infusions 4 or decoctions to be 0 tained in a continuous manner.

My invention consists in an apparatus in which the solvent and the material from which an extract, infusion 01'' decoction, is to be obtained, are made to travel in relatively opposite directions, the solvent --be-' comlng richer in or-more and more impregnated with the principles or qualities of the substance acted on whereas fresh material is constantly supplied to replace that whichhas become exhausted A very useful purpose to which my in vention may be applied is the dissolving out the sugary extractive contained in beets and in the accompanying drawing I have illus.- trated-merely by way of example-an ap i .paratus suited to that purpose .I wishlit,

however to -be lmd'erstood that-my invention .is not limited in its scope or applicatlon to the aforesaid purpose as it may be equally ;well employed in obtaining extracts, infusions or decoctions from other materials, for w example'to. mention only two'Peruvian 40 bark and logwood.

The material will be commmuted-by any usual and appropriate method to facilitate the solution of the extractive it contains.

' In the preferred constructional form of my invention the. apparatus comprises a .The material thus steeped in water" inthe said uppermost bucket will give up some of its extractive and the water will pass through the perforations to the bucket immediately Specification of Letters Patent.

below and there absorb or take '11 tive from the material contained therein. The'water thus passing through thewhole series of buckets constituting the, column will become increasingly rich.

Such a preferred constructional form of my lnvention is illustrated diagrammatically in side elevation in Figure l of the accompanying drawing, Fig. 2 being a secional left hand view on line A, B of Fig. 1.

The apparatus as regards its essential members comprises a series of cylindrical buckets '1, having perforated bottoms and carried between two: endless chains 2 by trunnions 3. The latter are provided with pmions 4: (one on each end) so that the extracbucket may be caused to tilt or even to make a complete rotation by the pinions engaging a rack or equivalent 10f proper lengt J The chains 2 are supported and driven by two toothed wheels 6 and at-their lower ends said chains wheels 8, a suitab e motor and its transmis- S1011 gear 5 imparting slow rotary movement to the wheels 6 in the direction of'the'arrow 7. It will be seen therefore that on the left hand side of Fig.1, there is a column of slowly ascending ,bucketsinto which suc-,

minuted beetis delivered- 10 through a chute 11. Each bucket as it cessively the material-for example comapproaches" the chute will be tilted shown at l w-by the engagement, on pass mg, of its toothed wheel or wheels 4- with a tooth or rack 9. Thus-inclining or tilting each bucket enables it the better to receivethe'material from the, chute; s

At" or near to the top of the apparatus is a water or other solvent supply pipe 15 which in the example nection with a'tank' or cistern 14.

ass over a pair of loose from a hopper lustrated ism con- Said pipe supplies water to the uppermost bucket of the column and this passes through the perforations to the next bucket below it and s j n throughthe whole series of buckets.

n. its

gradually enriched. until finally it is received in a vat 16 to be thereafter dealt with in any desired mariner.

The material will be more and more depassagethrough all the buckets. of the column-it will dissolve out some of the extractive contained in thematerial" in .each bucket and will .thus' be more or less pleted or exhausted of its extractive as the buckets reach nearer to the top of the column and it is to be considered desirable to make the apparatus of such dimensions as to the number of bucketscontained in the column and speed of movement, etc., that'the material will practically have had all its extractive dissolved out before the forthe time being uppermost bucket of the column moves to the position marked 1".

Simultaneously with the uppermost bucket moving away from the column of buckets with the exhausted matter, abucket will at the bottom of the column be brought into line and be supplied with'fresh material as describe As the bucket at 1 continues to move toward the right its pinions 4: will engage with racks 120i such length that the bucket will first be completely reversed--to thereby" empty it of the exhausted matterand then to bring it back to its normal position without strain. The material thus discharged is received in a hopper 13 and by a chute 14 is conducted away.

Instead of charging the buckets at the bottom of the ascending column they might be charged for example at the top of the descending column which would have the advantage/that the two columns of buckets all the latter charged with materialwould more or less better balance each other.

If desired the ascending column of buckets vent cooling of the contents and adapted, if

desired of having steam or hot air injected may be surrounded by a casing 18 to preinto it to impart heat to or to maintain the heat of the contents of the buckets. Or any other suitable means may be provided for heating and for maintaining the heat of the contents of the buckets.

A tank 17' may be provided to receive drippings from the descending buckets.

I claim: v

1. Apparatus of the class described comprising a continuous series of containers, means for-supplying material to be treated, successively, to the containers at the lower end of one reach of the series, means for supplying a solvent, successively, to the containers at'the upper end of said reach and means for positively rotating the containers after the application of the solvent to the material Within the containers.

2. Apparatus of the class described comprising a series of containers having perforated bottoms, means for supplying the containers with material to'be treated at the lower end of the series, means for supplying the containers With a solvent at the upper end of the series, and means for moving the series of containers upwardly vertically wherebythe solvent will pass, successively, through the containers from the upper to the lower end of the series.

In testimony whereof I affix my signature.
